JavaScript Frameworks - Heading into 2024

A year-in-review and forward-looking analysis of JavaScript framework trends by Ryan Carniato. Three major themes dominated 2023: the widespread adoption of Signals as a reactive primitive (Angular, Svelte 5, Lit, Vue), the maturation of hybrid server/client routing patterns (React Server Components, Astro), and the growing pains of edge computing (Vercel/Next.js pushing AsyncLocalStorage, Partial Pre-rendering). Looking ahead to 2024, fine-grained rendering via Signals is expected to reach full potential in Vue Vapor and Svelte 5, infrastructure-led differentiation between hosting providers will intensify, and AI integration into frameworks is on the near horizon. The overall trajectory is refinement rather than revolution, with the server-first paradigm now firmly established.
